Cheers~ computers can sacrifice for positional reasons. I suspect that part of the programs may play at least one of the gambits that you mrntion. Computers sometimes even play wrong sacrifices in the opening and I posted a game when list4.61(a strong engine without book) lost against tscp because of a wrong sacrifice in the opening. 1.e4 e5 2.Nf3 d5? exd5 e4? was the opening. There are programs that can play logical sacrifices like 1.e4 d5 2.exd5 Nf6 3.d4 both for white and for black My program Movei that is cearly weaker than the top programs but can sacrifice material for positional reasons. You can see that the public version after 1.e4 d5(if you do not use it's small book) may show the line exd5 Nf6 as it's main line at depth 11(at depth 12 it changes it's mind to exd5 Qxd5 but the scores for Qxd5 and Nf6 are almost the same). After 2.exd5 Nf6 it changes it's mind from 3.c4 (score 0.32 at depth 11) to 3.d4 (score 0.36 at depth 11 (the score goes down again to 0.32 at depth 12 but movei does not change it's mind and play d4 without book) Uri
