My teammate nairobigal defeated in this game a much stronger opponent!Well done!!! And many thanks to charleshiggie for the annotation!

The problem would be not so much this position as it would after 3...Nf6!?: e.g. 3...Nf6 4.e5 Ng4 5.Qe2. That line seems to me playable, but perhaps too committal too soon.

White could here have transposed into 'Open' lines by playing 4.d4.

It's more of a Wing Gambit, and not particularly good. Bc4 or d4 slightly better.

Objectively speaking, I agree with Kenneth, but there are subjective considerations that qualify my agreement. One is the development of a tactical imagination, and that is best achieved by placing a load upon it. GM Paul Keres (of whom I am still pretty much an admirer) recommended playing 'unsound' gambits by way of exercising the mind. If you can find a copy, I recommend Fred Reinfeld's book on Keres's games. The first dozen are correspondence games from the 1930s. They are most entertaining to play through...

no merit in h4 I agree.

Very well: but one has to ask: 'What was the purpose of this move?' I has to be said that it is hard to discern one! White has just given up a pawn, presumably for the sake of quick development and attack. That is the trade-off: material for time (and space). I reckon any of the moves 7.d4, 7.Bc4 and 7.Ba3 would have been worth considering as germane to the type of game White was looking for.

I would play 7..g6

Agree with 7..g6, the Dragon Bishop would have loved that diagonal with the b2 pawn out of play

In my view, a very interesting strategic decision. This sort of thing crops up frequently in other lines of the Open Sicilian: why not here? In all such instances, Black does have to be a little concerned about the 'backward' d-pawn, and the weak central light squares. Usually Black has compensatory advantages. The difference here is that White still has her d-pawn, and may, sooner or later, strike at Black's centre...

8.g3 is an error plain & simple. The pawn chain is aesthetically pleasing to the eye, but h4 does not need protection, and this move is too passive. Rb1 or Ba3 for choice here.

I agree with Kenneth. The main problem I have with 8.g3, is that it is too slow. I quite like 8.Ba3 here, attacking the loose knight, and preparing a central break by d2-d4, together with carrying on a quick deployment by Bc4. A possible line runs something like this: 8.Ba3 Nc6 (NOT ...Qa5; ...) 9.d4 Bg4 (taking advantage of the fact that White can't swat the bishop away by playing h3) 10.d5 Nd4 11.Qd3! Nxf3ch 12.gxf3 Bd7 In a position like this, White's powerful centre makes up for deficiencies on the wings.

Bg4 or Be7, both are good alternatives

a too simplistic way of attacking. no danger on f7. again Ba3, trying for the initiative. f7 is too easy to defend here.

Here I somewhat diverge from Kenneth's view. The f7-square is not the only target, but the whole light square complex in the centre. Having said that the move has a very serious tactical downside that White needed to be aware of. Look at the b4-knight. It strikes at the c2-square, which is defended by the Queen. Were Black now to play 9...Bg4, it would be attacking the f3-knight, which is defended... by the Queen. Black would be threatening ...Bxf3; Qxf3 Nxc2ch; ...Nxa1. The only good defence, then, would be 10.Be2.

black is worried about Ng5

A better, and more active, defence against Ng5 would have been 9...Bg4, threatening to win material, and more-or-less forcing White to play 10.Be2. White COULD try 10.Bb5ch, but Black might well be happy enough to respond by 10...Ke7 11.0-0!? Nxc2!? 12.Qxc2 Bxf3 and now, supposing White were to play 13.Bc6 ... with the view to forcing the rook away from protecting the a-pawn, Black can counter-attack by 13...Qc8! with the idea 14.Bxa8?? Qh3!

That train may have already left the station

Black should not be looking to ...Bg7, but ...Be7. This pawn advance does constrain Black's K-side, but Black should be more interested in operations in the centre of on the Q-side. 10.Ba3 still looks good.

This development carries the threat I mentioned before: to win a piece (11...Bxf3 12.Qxf3? Nxc2ch).
