Canadian Open - round 4 - some games

[Hugh Brodie]

Here are boards 2 to 5 that were presented live. Board 1 is still in progress as I write, but the transmission died at move 43. Note that these games as well might not be complete - I can't tell until I see the scoresheets. (ATTN organizers - will these be available soon/when?)

Curious line spotted after 16....Bc5. These moves aren't optimal, but the play also isn't refuted by the computer:
17. Rb2 Bxf2 18. Rf1 Bb6 19. Bxf7+ Kxf7 20. Nxe5+ Ke6 21. Nxg4.
