Well guys, seems Houdini thinks different. In this position he points Bd3 in an equal position = 0,08. In fact Blacks are well positioned and castled. If playing correctly by blacks it is a draw game!!!

Cool.

How long did your houdini engine analyze the position?
How many plys were reached?

Thank you.

This is really impressive closed system you play Ahmed Kamal.

I use this system when i play against Stockfish (or any other strong engine). But I generally play the king's gambit when l play against my friends.

Do you prefer to play either King's Gambit Declined or King's Gambit Accepted?

I do have to admit that Stockfish does seem to evaluate positions (generally) more optimiscally than Houdini does. It's almost by a full pawn! So, perhaps Houdini's evaluation may be more correct.

the Falkbeer Countergambit is a dubious defense for Black.

I think agreed with other opinion that Falkbeer Countergambit is the best answer for KG !? Without loss of movement but difficult playing of sharp game at the beginning!
