Philidor's Defense. Not too common, but solid nonetheless.

Surprisingly, perhaps, I prefer 3.d4, here.

Premature. Actually h5 is not too uncommon in such openings but it comes later, usually preceded by ...g6.

Neglecting development, always a bad thing.

What would you do after he played 5...c6? It's good that you think this way but your knight on d5 is vulnerable and c6 drives it away, perhaps even followed by b5, further repressing your pieces and claiming space.

I agree with sonata296: 5...c6! would have been a very good response.

Well spotted!

Very good move! At once Nxc7ch?? would have been silly in the circumstances. Joe, this really is a 'fork', the bishop is attacking King and Queen both. But it is also a decoy to lure the Queen into another K-Q fork. Very nice - and deadly - piece of tactics.

7.Kd8 is better, to free up the Q-side for mobilisation. But Black has a losing game, now, whatever he does.

At this point the game for black is lost, so the difference is pretty small. EDIT: I did not imply anything, I was just pointing out that with good play black is lost either way, so the difference between Kd8 and Kd7 is small, but it is there, I agree. Always fight till the end.

This move is a little risky, as it opens up the possibility of Nb5-c3-d5-b6ch and another fork!

I would have been very tempted to play 10.Nd5 here. ************ Response to isaiah11: Objectively speaking, and all things being equal, 10.d4 is likely the better option. But the material imbalance alters the nature of the game: things are no longer 'equal.' White can 'get away' with non-optimal moves in the interests of bringing on further crises, and placing the opponent under pressure trying to save an unsalvageable game. 10.Nd5 would practically force 10...Kc6 as any other response would allow White at the very least to exchange the knight for the c8-bishop. The loss of time scarcely matters: look at Black's development now! After 10...Kc6, a King hunt becomes possible: 11.c4!? Nf6 (say) 12.Qa4ch Kc5 13.b4ch Kxc4 14.b5ch Kd3 (14...Kc5 15.Ba3#) 15.Kd1! ... 16.Qc2#. My point is, when the game takes an unusual turn, often the usual 'rules' cease to apply.
