Hi and welcome.
Your thought processes on the game indicate some ability to me, particularly with the use of your troublesome bishop, but it's difficult to gauge your level on the basis of one game of course.
Drop me a 3/7 challenge if you like, provided you don't use electronic assistance. I've played here for several years and despite playing like a complete dunce at times, I think my own rating is probably about right.
A very large proportion of players here inhabit the 1400-1600 bracket.
Beware players with high amounts of concurrent games with few/no losses, for obvious reasons.
